Looking at the front coilover conversion kit for my 68 Barracuda. Any pros/cons going with either the 0-2in or 2-4in drop option? What is the difference between the single and double adjustment set up? Any significant modifying to make it work or is it a pretty straight forward bolt in system? Any rear suspension upgrades that would need to compliment the front? Also, any header fitment issues? I currently have Hedman tight tubes where the exhaust after the header flange slightly touches the tie rod ends.
